WINDOW.

Applcationled September 18, 1919.

The invention has forl an object to pro-` vide a novel construction and relativev ar-v rangement of the j amb members of the frame and the sash members to insure the line contact and be capable of embodiment generally in windows having sliding sashes.

The invention has for a further ob] ect sto provide meeting rails of novel form arranged to insure line contacts therebetween whenv Y by screws 23 or other suitable fastening the sashes are in the closed position.

More speeiiically, the invention has for its object to provide an embodiment of the in'- Y vention reflecting important considerations with respect to simplicity and durability and the convenience of installation and the partial or complete disassembling of the same for repairs or the like. v

The invention consists in a window having the novel features hereinafter particularly described and claimed. l

Reference is to be had to the accompany- V ing drawings forming a part of this speci fication, it being understood that the drawings are merely illustrative of one example of the invention. 4

Fig. 3 is a detail view in horizontal section showing a modified form of one of the vertical side members of the window frame; and

In carrying out my invention in accordance with the illustra-ted example, la metal window frameis provided comprisingl a top bar or frame-head 10, a bottom bar or sill 11, and vertical side bars or jambs 12 and 13` The form of window shown in the illus* trated example of my invention is the panel type in which there are side jambs and in- Specfication of Letters Patent.

termediate jambs and one or more of the sashes in the window may be `sliding and one or more liXed. In the form shown in Figs. 1 and 2, the intermediate jamb 13 is hollow, composed of two channel bars united face to face to form a tubular jamb. The jambs have novel guide members as will appear for the upperand lower sashes 14,15. For illustration, the sashes are sho-wn as of the counterbalanced type, as distinguished from the counterweighted type. A chain 17 is secured at one end to a. bracket or plate 16 on lower sash 15, said chain running over a pnlley 18 and here shown as secured by a screw 19 to the horizontal flange of an rangle bracket 20 on upper sash 1li and provided with set nuts 20, 21above ,and below the bracket. e

Parting strips 22are provided in the form of channel bars secured to the iambs 12, 13

mea-ns. inner stops 24 are Z-shaped in cross section and secured by screws 25 or the equivalent. Similarly, outer stops 26 are employed, Z-shaped in cross section, one flange of each of which is secured by screws 27 or the like to the jamb.` To add to the weather-tight qualities of the window,y simi-l lar bars 28', 30, Z-shapedin cross section, are :similarly` placed across thev frame-head1() at the outside, and across the sill 11 at the inner side, and secured byscrews29, 31,

respectively, to be in Contact withV the sash frames when closed. Screws 25, 27 securing the stops to the channel bar jambs 12, 13 take into lateral flanges 33 directed llaterally outward on said jambs and in the case of the intermediate jamb 13 the two opposed U- shaped channel members forming the same have their flanges 33 directed laterally outward on said jambe and in the case of the intermediate jamb 13 the two opposed U- shaped channel members forming the same have their flanges 33 united byv suitable The screen at vthe bottom may be held in any approved manner. Inner and outer stops 24, 26 and the cross bars 28, 28a

and 30 have slots 32 therein through which the fastener screws are passed, the slots permitting said lstops and cross bars to beadjusted toward and from theV sashes to effect n channel bar 34 having a narrow flange 35 and a wider flange 36, the edges of the latter extending into channels ell.v formed by the stops 24, 26 and the adjacent sides of the channel jambs7 the inner4 flanges 2a, 26 of the respective stops being'disposed toward the sides of said jambs and presenting narrow throats snugly accommodate the wider flanges 36 of the sash frame members, and said throats may be made wider or narrower by adjusting the stops; said arrangement serves to produce an effective guiding of the sash in the window frame. An important factor entering into my improved window resides in the relative form of the sash frame members 34 and the guiding members on the window frame engagec'l by the sash frame members. It will be observed that the inner surface of a flange 36 and the opposed surface presented by the side of a jamb flare, the result being produced by one or both of said surfaces' being made oblique; in the illustrated form the langes 36 taper to give the desired result and it will be seen that the line' contact with the Channel bar jambs 12 and 13 is therefore along a line at the adjacent angles presented by said jambs, that is to say at the base of the flanges of said channel bars. There is essentially a line contact produced` also ,be-

tween the outer surfaces. of the flanges 36 and the inwardly disposed flanges 24a, 26 of the stops. Similarly, a line contact is effected between the shorter flanges 35 of thev sashes and the channel parting strips 225 for which purpose the members of the parting strips taper outwardly. It is to be noted that the flanges of the parting strips 22 are directed outwardly and the outer surfaces are outwardly converged, also theflange 35 tapers and the line Contact isat the base of the flanges on Vstrips22j rIhe bottom cross bars or strips 28a, 30 and the top cross strip 28 similarly make close contact when engaging the cross bars of' the sash framesl the top and bottom channel rails `and the meeting rails of which are formed as next described. j

The meeting rails37 of the sashes are in the form of channel bars presenting at the outside comparatively narrow flanges and at thejinsi de opposed wider flanges 39. The flanges 39 are curved laterally `as` at 40`to overlap in the plane of the parting strips 22 andthey presentopposed curved surfaces. so that the edges of said flangesBO will produce liiiecontacts to effect a tight' engagement of the meeting railli. V railln of the outer sash is channeled cor-responding substantially with the Y meeting rails`37 and presenting a narrowflange 53S and a wider flange 39a which curves laterallyI inward at its free edge as at 40a, presentinga convex surface to engagey with the lintel or top bar l of the window fra-.me by The top bar or' substantially a line contact, said top bar having the inner and outer portions in different horizontal planes and joined by an oblique portion l()u with which the curved portion 48a contacts. The top bar 26 makes a close contact with the flange 38, the contact being insured by the adjustment of said top bar by screws 29. Similarly, the bottom rail or cross bar 37b of each lower bar is in the form of a channel bar presenting a narrow flange 38h to be engaged by the bottom cross strip 30 and a wider flange 39h, the lower portion of which is curved as at to contact with -the oblique portion 11a of the sill 11.

The above-described construction, it will be seen` provides a secure retention of the sashes, an effective guiding thereof. in the window frame with the desired close joints between the sashes and frame parts, and the construction insures strength and durability and involves few parts of minimum simplicity. 1 i

yWhen the sash at one'side of the intermediate jamb 13 is fixed, instead of sliding` saidv jamb may be arranged as in Fig. 4i in which a channel jamb member 13 as de; scribed with flanges 33 isprovided at one side with stops, the outer stop 26 and one of its securing screws 27 beingindicated in Said j figure. The fastening screws serve to secure to .the channel jamb member 13 a plane plate l12 closing thc channel, the securing screws passing through vsaid plate andthe flanges of said channel jamb member.' The adjacent channel bar 34a of the sash `15a has flanges 35a, 36a whichmaykbe of equal length, the saidchannel bar beingsecured by screws, one screw being indicated atf 44. A Hat` plate 4:?) secured by a rivet 44@ or other per; manent fastening V,means'may proyided, disposed between the'flanges 35, 36H1 The form showninFig. 3 provides for an enlarged intermediate jamb, the channel j amb members 13 having interposed between their flanges thereof ya channel bar l5 secured to the flanges 33 by suitable fasteners 46. j A j I would state in conclusion that while the.` illustrated example constitutes a practical embodiment of my invention, I do not Alimit myself strictly to the mechanical details herein' illustrated, since manifestly the same can be considerably varied `without departure from the spirit ofthe invention as defined in the appended claims. j
